Huge fixes to glibc build, so that we can build at least (and at last):
- use ports addon even when installing headers,
- use optimisation (-O) when installing headers, to avoid unnecessary warnings (thanks Robert P. J. DAY for pointing this out!),
- lowest kernel version to use is only X.Y.Z, not X.Y.Z.T,
- a bit of preparations for NPTL (RSN I hope),
- fix fixing the linker scripts (changing the backup file is kind of useless and stupid);

Shut uClibc finish step: there really is nothing to do;

Add a patch for glibc-2.3.6 weak aliases handling on some archs (ARM and ALPHA at least);

Did not catch the make errors: fixed the pattern matching in scripts/functions;

Introduce a new log level, ALL:
- send components' build messages there,
- DEBUG log level is destined only for crosstool-NG debug messages,
- migrate sub-actions to use appropriate log levels;

Update the armeb-unknown-linux-gnu sample:
- it builds!
- uses gcc-4.0.4 and glibc-2.3.6,
- updated to latest config options set.

I would like to thank these fine people for making crosstool-NG possible:

  Dan KEGEL, the original author of crosstool: http://www.kegel.com/

    Dan was very helpfull and willing to help when I build my first toolchains.

    I owe him one. Thank you Dan!

    Some crosstool-NG scripts have code snippets coming almost as-is from the

    original work by Dan.

  Allan CLARK for his investigations on building toolchains on MacOS-X.

    Allan made extensive tests of the first alpha of ct-ng on his MacOS-X

    and unveiled some bash-2.05 weirdness.

  Enrico WEIGELT for some improvements of the build procedure:

    - cxa_atexit disabling for C libraries not supporting it (uClibc)

  Robert P. J. DAY:

    - some small improvements to the configurator, misc prompting glitches

    - 'sanitised' patches for binutils-2.17

More to come as they help.
